Specification of uLetters Patent. I Fatengd July .La 19111 .Application filed September 20, 1910. 'Serial No. 582,909.

To all wlw/om 'it may concern:

Be it known that L'Eowano ll; JoifiNsoN, a citizen of the United States, residing, at Los Angeles, in the county of Los Angeles and State of California, have invented a new :ind nseiful llireproof llindovv.- Cdash, of which the 'Following is a specification.

lhs invention relates to the construction of Window str-.shes of sheet metal in suoli manner as to be substantially hre proof, and the invention relates particular-hT to nueans for enabling;` the panes to be pnt in place in the sash and to be retained therein.

The main object of the present invention is to provide a metallic sash construction in which the use o'l removable or separate Inullions is obviated, and a firmer and more lire proof construction o1" the innllion is thereby obtained.

Another objeet of the inventinni is to provide ineans for holdinip; the panes in suoli manner that the usual provision ol" n Lt'ree space et one edge of the pane is dispensed with, therebj)T enabling the pane to be held more l` only El. further object of the invention is 'to provide a sesh construction wherein the een be inserted by a dire-et slidingr rnotion Without necessitating the twowvay movement generally required for such insertion..

@their objects of the invention willappear hereinafter.

The aecoinpnnying drawings' illust-rate any invention. l

Figure 1 is a perspective oit the rear of the sash. body vwith a dotaehnble side ineniber thereof removed. l is a perspective ot' the said detachable side member. lig. 3 is persoeetive ot' o looking` strip t'or securing said ineinberto said side bod'uv. ligfl is a partial vertical section of the sash on line 'L-fct in Fig. 1. Figa 5 is a horizontal section on the line :irerin Fig. 1, Withihe side inem-- ber in position; Fogli 1s a horizontal :seo

tion on lino mier/"5' in Fig. 1, with the side- The said rails are formed out sheet meta-l bent to form e tubular construction.V Walls of seid tubular construction oon'iprise front Walls 5 and rear Walls 6 with eoinnet.-` ing-plates 6', said front and rear vz lls having inwardly extending' flanges l' lnwiinr portions 7 extendingintol proximity and in parallelism and with 'their edges seai'ned together at 9 to 'forni a U-sliaped portion if'orx'ninga groove l2 between the portions 7 for receiving the sash panes' 8.

The incomplete rail portion 4E is preterably provided nt the front side of the sash frame and is connected at its ends to the rails 2 and 3. Fig. 1 of the drawings shows the sash arranged with this ineoniplete or open side of the frame at one side, but it Will be understood that this open rail may be at the top or in any position according to the direction in which the sash stands, and when the sash is turned with its in ullions extending' vertically, as will gerieralljvY be the c'ase, .this open rail of the seslrtvill be at the top. l

The inullion comprises front and roer strips, the front strip 10 extending between the side members of thek front pla-te and preferably extending behind the side plate l of the body. A rear inullion inesnber 11 is connected at one end to the rear plate t3 at one side of the body and extends across the glass receiving yspace and parallel to the front inullion member. Both of said n'ioli lion members are provided with llanged por tions 13, extending inwardly toward the pane and then parallel to the pane as et 13 and having their end portions interloet d or seainled togethenas shown ot Lt grooves l5 between the parallel portions 1er ot said llanges. The grooves 12, 15x-'formed between the parallel portions of the re speetive flanges 7 and 13 and bounded by the interlocking or seanled portions 9 and 1e connecting said flanges, form guides for receiving and guiding the edges of the glass pane S which is adapted to be slid into said spaces. A. reinforcing plate 17 is provided within the hollow lnlillion member 1 0, and is provided with a screw threadedhole 17. said plate being behind the side plate al of the sash body.

The

The rear porti-on of the sash body is ont away at the open side of the body and the rails 2 and l are provided with extensions 18 and 19 extemhng at. the rear of the 51de member of. the sash body and laiearrisf2i-0 are' v5,1ow the respectifsJ `extensions 18, 19 afore-A said; Reinforcing plates 22 are secured, as by: vmeans of rivets 23, to the respective plates or extensions 18, 19 of the rails 2 and 3 oft-he body, these plates being tapped or provided with screw-threaded perforations 21.

The. removable rail member 24 ofthe winl 'dow frame is L portion 25I Whic is adapted'to slide laterally in .front .of the extensions .18, 19 aforesaid,

lpthee'nds of said rear plate portion sliding within the seams on the body member 1, and being preferably bent or turned 'over as at 26 to interlock or form a slidingr joint with said seams. Said rail member is 20 further provided with a flange 27 extending forwardly therefrom and terminating in a flange 28, parallel to the front plate 25, said fiange 28 being formed by bending over andv doubling the end ofsaid'I flange 27 and y being adapted to engage a groove 29 formed by turning over a flange 30 extending rearwardly from the front plate 4 of the' body member. Said side portion is further provided with flanges extending 30 obliquely inward and bent at their ends in U-shape to form grooves 33 for receiving the edges of the glass panes, these grooves being formed between parallel portions 35, 36 of said flanges 32, the forwardiparallel portion 36 being cnt away as shown at 37 to fit the.

forward front mullion member 10 and the obliquely 'extending flange 32 being cut away as shown at 38 to lit the rear mullion member 11. Plat-e 25 of the side member is l40 bent as at 25 to enter a fold 18 in the front plates ofthe top'and bottom members 2 and 3. The lolking member or strip 40. is formed wit a fold or U-shapedbend 41 along each side, one of saidbends extending 45 within the other so las to adapt the strip to be slipped over the fiange and around the groove portion 29 of V"the flange 30 on the body of the frame so asto interlock the side member and the body of the frame-.together. Y. The frame is 'assembled as-fol-lows: The

side of the frame being open as shown in Fig.

1 the glass plates 8 are slipped sidewise into the channels `or grooves 15 formed between the fianges 13 of themullions and within the grooves 12 formed between the flanges 7 of the body. The side member 24 isslthen put in place by sliding it laterally on the body, the rear plate 25 of said member'sliding on the extensions 18, 19 and within the seam portions 20 on saidbody, the bends 26j on said sidemember interloclred or seaming with the said seam portions on the body. When thev side member has thus been 035 brought to proper position, the flanges 32 rovided 'with a rear plate thereonwill embracethe edge of the lass and hold the same firmlyin place an the fiange 28 on said side member will enter the lgroove 29 on the body member. Said arts are then locked together by slidingthe ock- 70 ing strip 40 endwise over 'the' groove portions 29 of thebody member withits inner flange or fold engaging within the doubled flange.28 of the side member. This rigidly A secures the sidev member tothe body, member 715' at the frontportion thereof. In order'\ to more fedectu'ally lockthe parts' together'V at the rear portion, screws indicated at 43 a're inserted through thexmovable side member and screwed into the openings 21 in the eX-l 80 tensions 18, 19- of the body member and ascrew 44 is also inserted through said side member and through the perforation 21 lin the rear mullionll screwing into the hole' 17 in reinforcing plate 17 inthe front mul-4 85 lion member.
